[0002] Currently, the control of the sinter bin level in the sintering system is a key control aspect of the sintering production process. Due to the small size of the bins, levels that are too high or too low can easily cause shutdowns or even production accidents in the sintering system. Therefore, existing methods for controlling the bin level in sintering systems suffer from technical problems such as poor operational stability. Summary of the Invention

[0003] This application provides a method, apparatus, and readable storage medium for controlling the ore bin position in a sintering system, which addresses technical problems such as poor operational stability in the prior art.

[0004] A first aspect of this application provides a method for controlling the position of a sintering bin in a sintering system. The sintering system includes a sintering bin, a sintering machine, and a conveying device. The sintering bin is used to receive and store sintering mixtures, and the conveying device is used to convey the sintering mixtures in the sintering bin to the sintering machine. The method includes: During the operation of the sintering system, the first slot position of the ore bin, the first sintering speed of the sintering machine, and the first transmission speed of the transmission equipment are obtained, as well as the target slot range corresponding to the ore bin and the second slot position of the ore bin in the previous production cycle are obtained. Under the condition that the first slot does not exceed the target slot range, determine the slot deviation between the first slot and the target slot, and determine the slot change between the first slot and the second slot. The target slot is the median value of the target slot range. The second sintering speed corresponding to the sintering machine is determined based on the slot deviation, the amount of slot change, and the first sintering speed. The second transmission speed corresponding to the transmission device is determined based on the first sintering speed, the second sintering speed, and the first transmission speed; Adjust the sintering speed of the sintering machine to the second sintering speed, and adjust the transmission speed of the transmission equipment to the second transmission speed.

[0005] The method for controlling the sintering system trough position in this embodiment determines the trough position deviation between the first trough position and the target trough position during the operation of the sintering system, and determines the trough position change between the first trough position and the second trough position, thus ensuring the accuracy of the trough position deviation and trough position change data.

[0006] Based on the accurate slot deviation and slot change, the first sintering speed is updated to the second sintering speed. Then, based on the first sintering speed and the second sintering speed, the first transmission speed is updated to the second transmission speed, ensuring the accuracy of the data for the second sintering speed and the second transmission speed.

[0007] Adjusting the transmission speed of the transmission equipment to the second transmission speed ensures the stability of the sintering machine's feed, so that the sintering machine is in the most stable feeding state. Adjusting the sintering speed of the sintering machine to the second sintering speed ensures the sintering stability, so that the sintering machine is in the most stable sintering state.

[0008] In summary, by precisely controlling the sintering speed of the sintering machine and the transmission speed of the conveying equipment, the first position of the ore bin is always kept in an optimal state close to the target position. This ensures that the ore bin and the conveying equipment can continuously and stably supply material to the sintering machine, avoid sintering machine shutdown failures, and thus guarantee the overall operational stability of the sintering system.

The device includes: The acquisition unit is used to acquire the first slot position of the ore bin, the first sintering speed of the sintering machine and the first transmission speed of the transmission equipment during the operation of the sintering system, and to acquire the target slot position range and the second slot position of the ore bin in the previous production cycle. The first processing unit is used to determine the slot deviation between the first slot and the target slot, and to determine the slot change between the first slot and the second slot, provided that the first slot does not exceed the target slot range, and the target slot is the median value of the target slot range. The second processing unit is used to determine the second sintering speed corresponding to the sintering machine based on the slot deviation, the amount of slot change and the first sintering speed; The third processing unit is used to determine the second transmission speed corresponding to the transmission device based on the first sintering speed, the second sintering speed, and the first transmission speed. The control unit is used to adjust the sintering speed of the sintering machine to the second sintering speed and the transmission speed of the transmission equipment to the second transmission speed.

[0016] In some embodiments, such as Figure 1 As shown, an embodiment of this application provides a method for controlling the position of a sintering system ore bin, including: Step S101: During the operation of the sintering system, the first slot position of the ore bin, the first sintering speed of the sintering machine, and the first transmission speed of the transmission equipment are obtained, and the target slot position range corresponding to the ore bin degree and the second slot position of the ore bin degree in the previous production cycle are obtained. Step S102: Under the condition that the first slot does not exceed the target slot range, determine the slot deviation between the first slot and the target slot, and determine the slot change between the first slot and the second slot. Step S103: Determine the second sintering speed corresponding to the sintering machine based on the slot position deviation, slot position change, and first sintering speed; Step S104: Determine the second transmission speed corresponding to the transmission device based on the first sintering speed, the second sintering speed, and the first transmission speed; Step S105: Adjust the sintering speed of the sintering machine to the second sintering speed, and adjust the transmission speed of the transmission equipment to the second transmission speed.

[0017] In this embodiment, a method for controlling the position of the sintering bin in a sintering system is proposed. The sintering system includes a sintering bin, a sintering machine, and a conveying device. The sintering bin is used to receive and store the sintering mixture, and the conveying device is used to convey the sintering mixture in the sintering bin to the sintering machine. The sintering machine is used to sinter the sintering mixture into blocks.

[0018] For example, the sintering mixture may specifically be a mixture of iron concentrate powder, rich ore powder, return ore and iron-containing waste.

[0019] For example, the ore bin can specifically be a sintering ore bin, used to temporarily store the prepared sintering mixture.

[0020] For example, the sintering machine is a core piece of equipment in the steel industry used to sinter raw materials such as iron ore powder and coke powder into lumps, and is widely used in the raw material processing stage before blast furnace ironmaking. The sintering machine is mainly used to mix fine-grained iron concentrate powder, rich ore powder, return ore, and iron-containing waste, and then partially melt and bind them into porous, blocky sintered ore at high temperatures. This process not only improves the particle size and strength of the raw materials but also enhances their reducibility and permeability, ensuring the stable and smooth operation of the blast furnace. Simultaneously, the sintering process effectively removes harmful impurities such as sulfur and phosphorus, and achieves comprehensive resource utilization.

[0021] For example, a sintering machine may specifically include a trolley, a transmission device, a material feeding system, an igniter, and a ventilation and dust removal system.

[0022] Trolley: A key component that carries the sintering mixture. It consists of a cast steel body, slats, rollers, and sideboards, and must be resistant to high temperatures and deformation.

[0023] Transmission device: Flexible transmission technology (such as two-point meshing or double-envelope worm gear transmission) is adopted to ensure smooth operation and reduce the impact of thermal expansion.

[0024] Fabric distribution system: including shuttle fabric distribution machine and roller fabric distribution device, to achieve uniform distribution of mixed material along the length and width of the trolley.

[0025] Ignition device: It uses multiple rows of burners to ignite the surface mixture at high temperature, ensuring complete combustion.

[0026] Ventilation and dust removal system: The system uses a large flue and a negative pressure ventilation box to promote the sintering reaction and is equipped with environmental protection facilities such as electrostatic precipitators and desulfurization towers to control emissions.

[0027] For example, the conveying equipment can specifically be a belt conveyor, which includes round rollers. The rotation of the round rollers drives the feed plate to reciprocate back and forth, gradually pushing out the lumpy or granular material in the ore bin. The conveying equipment features large conveying capacity, long conveying distance, and high efficiency. It can realize intelligent control and unattended operation, and supports horizontal or inclined layout.

[0028] During the sintering process of the sintering system, the first position of the ore bin, the first sintering speed of the sintering machine, and the first transmission speed of the transmission equipment are detected respectively. The first position is the real-time position value of the ore bin, the first sintering speed is the real-time sintering speed of the sintering machine, and the first transmission speed is the real-time transmission speed of the transmission equipment.

[0029] For example, the unit of the first tank can be specifically tons, specifically 40 tons.

[0030] For example, the unit of the first sintering speed can be specifically tons per minute.

[0031] For example, the unit of the first transmission speed can be specifically tons per minute.

[0032] Obtain the target slot range corresponding to the ore bin degree and the second slot of the ore bin in the previous production cycle. The target slot range is the safe range that ensures the ore bin can provide sintered mixture, and the second slot is the historical slot value of the ore bin in the previous production cycle.

[0033] For example, the second slot can be specifically the average value of the measured slots in the previous production cycle.

[0034] For example, the second slot can be specifically the median of the measured slots in the previous production cycle.

[0035] For example, the target sintering tank range can be specifically 48 tons to 52 tons. The target sintering tank range can ensure that the ore bins provide sufficient sintering mixture to the sintering machine so that the sintering machine can operate continuously and stably, avoid sintering machine shutdown problems, and thus avoid sintering machine production accidents.

[0036] For example, if the first slot of the ore bin is less than the lower limit of the target slot range, it will cause the sintering machine to have insufficient feed, which will in turn cause the sintering machine to stop.

[0037] For example, if the first slot of the ore bin is larger than the upper limit of the target slot range, it may cause the sintering machine to have too much material fed in, or it may cause the sintering machine to stop.

[0038] Under the condition that the first slot does not exceed the target slot range, determine the slot deviation between the first slot and the target slot, and determine the slot change between the first slot and the second slot. The slot deviation is the difference between the first slot and the target slot, the slot change is the difference between the first slot and the second slot, and the target slot is the median value of the target slot range.

[0039] For example, if the target tank capacity ranges from 48 tons to 52 tons, the target tank capacity can be determined to be 50 tons.

[0040] For example, if the target tank capacity ranges from 50 tons to 52 tons, the target tank capacity can be determined to be 51 tons.

[0041] For example, maintaining the first position of the ore bin at the same level as the target position can ensure the stability of the feed rate to the sintering machine, thereby ensuring that the sintering machine is in the most stable operating state.

[0042] Based on the slot deviation, slot change, and first sintering speed, the corresponding second sintering speed of the sintering machine is determined, where the second sintering speed is the target sintering speed value of the sintering machine.

[0043] For example, the second sintering speed is the optimal sintering speed that can ensure the stable operation of the sintering machine.

[0044] Based on the first sintering speed, the second sintering speed, and the first transmission speed, the second transmission speed corresponding to the transmission equipment is determined, wherein the second transmission speed is the target speed value of the transmission equipment for transmitting the mixture.

[0045] For example, the second transmission speed is the optimal transmission speed that can ensure stable feeding of the sintering machine.

[0046] Adjusting the sintering speed of the sintering machine to the second sintering speed and the transmission speed of the conveying equipment to the second transmission speed can ensure the stability of the sintering machine's feeding and sintering.

[0047] The method for controlling the sintering system trough position in this embodiment determines the trough position deviation between the first trough position and the target trough position during the operation of the sintering system, and determines the trough position change between the first trough position and the second trough position, thus ensuring the accuracy of the trough position deviation and trough position change data.

[0048] Based on the accurate slot deviation and slot change, the first sintering speed is updated to the second sintering speed. Then, based on the first sintering speed and the second sintering speed, the first transmission speed is updated to the second transmission speed, ensuring the accuracy of the data for the second sintering speed and the second transmission speed.

[0049] Adjusting the transmission speed of the transmission equipment to the second transmission speed ensures the stability of the sintering machine's feed, so that the sintering machine is in the most stable feeding state. Adjusting the sintering speed of the sintering machine to the second sintering speed ensures the sintering stability, so that the sintering machine is in the most stable sintering state.

[0050] In summary, by precisely controlling the sintering speed of the sintering machine and the transmission speed of the conveying equipment, the first position of the ore bin is always kept in an optimal state close to the target position. This ensures that the ore bin and the conveying equipment can continuously and stably supply material to the sintering machine, avoid sintering machine shutdown failures, and thus guarantee the overall operational stability of the sintering system.

[0051] In some embodiments, this application provides a method for controlling the position of a sintering system ore bin, which determines a second sintering speed corresponding to the sintering machine based on bin position deviation, bin position change, and a first sintering speed, including: Determine the corresponding speed adjustment value for the sintering machine based on the slot deviation and the amount of slot change; Obtain the adjustment coefficient corresponding to the speed adjustment value; The second sintering speed is determined based on the first sintering speed, the speed adjustment value, and the adjustment coefficient.

[0052] In this embodiment, the speed adjustment value corresponding to the sintering machine is determined based on the slot deviation and the amount of slot change, wherein the speed adjustment value is the adjustment value corresponding to the first sintering speed.

[0053] For example, the formula for calculating the speed adjustment value can be: A=K1×e+(1-K1)×ec, where A is the speed adjustment value, K1 is the deviation ratio coefficient, e is the slot deviation, and ec is the slot change.

[0054] The deviation ratio coefficient is a weighted calculation coefficient between the slot deviation and the slot change, used to represent the relative importance of the slot deviation and the slot change.

[0055] For example, when the slot deviation is greater than the slot change, the deviation ratio coefficient can be set to 0.7.

[0056] For example, when the slot deviation is less than the slot change, the deviation ratio coefficient can be set to 0.3.

[0057] Obtain the adjustment coefficient corresponding to the speed adjustment value, and determine the second sintering speed based on the first sintering speed, the speed adjustment value, and the adjustment coefficient, wherein the adjustment coefficient is the speed adjustment coefficient corresponding to the speed adjustment value.

[0058] For example, the formula for calculating the second sintering rate can be: V 调整后 =V+K V1 ×A, where V 调整后 V is the second sintering speed, and K is the first sintering speed. V1 A is the adjustment coefficient, and A is the speed adjustment value.

[0059] For example, the adjustment coefficient can be determined based on the value of the first sintering speed. When the first sintering speed is greater than the preset speed value, the adjustment coefficient is determined to be 0.2, and when the first sintering speed is less than or equal to the preset speed value, the adjustment coefficient is determined to be 0.8.

[0060] For example, the adjustment coefficient can be determined based on the value of the speed adjustment value. When the speed adjustment value is greater than the preset value, the adjustment coefficient is determined to be 0.3, and when the speed adjustment value is less than or equal to the preset value, the adjustment coefficient is determined to be 0.7.

[0061] For example, the adjustment coefficient can be determined by comparing the speed adjustment value and the first sintering speed. When the speed adjustment value is greater than the first sintering speed, the adjustment coefficient is determined to be 0.3, and when the speed adjustment value is less than or equal to the first sintering speed, the adjustment coefficient is determined to be 0.7.

[0062] In some embodiments, this application provides a method for controlling the position of a sintering system ore bin, which determines a second transmission speed corresponding to a transmission device based on a first sintering speed, a second sintering speed, and a first transmission speed, including: Determine the ratio between the first sintering rate and the second sintering rate to obtain the rate ratio; The product of the first transmission speed and the speed ratio is determined to obtain the second transmission speed.

[0063] In this embodiment, the ratio between the first sintering speed and the second sintering speed is determined to obtain a speed ratio, wherein the speed ratio is the ratio between the first sintering speed and the second sintering speed.

[0064] The product of the first transmission speed and the speed ratio is determined to obtain the second transmission speed.

[0065] For example, the second transmission speed may be specifically the rotational speed of the rollers of the transmission device.

[0066] For example, the formula for calculating the second transmission speed can be: S 调整后 =(V 调整后 ×S) / V, where S 调整后 For the second transmission speed, V 调整后 S represents the second sintering speed, and S represents the first transport speed.

[0067] In some embodiments, this application provides a method for controlling the sintering system ore bin position, obtaining a target ore bin position range corresponding to the ore bin degree, including: Get the maximum capacity of the mining tank; Determine the target slot range based on the maximum capacity.

[0068] In this embodiment, the maximum capacity of the mining tank is obtained, wherein the maximum capacity may specifically be the maximum rated capacity of the mining tank.

[0069] For example, the maximum capacity can be specifically 50 tons.

[0070] Determine the target slot range based on the maximum capacity.

[0071] For example, by determining the maximum and minimum coefficients respectively, the upper and lower limits of the target slot range can be determined based on the product of the maximum and minimum coefficients and the maximum capacity.

[0072] In some embodiments, this application provides a method for controlling the position of a sintering system ore bin. When a first bin position exceeds the target bin position range, the method further includes: Obtain the initial feed rate of the ore bin; Determine the change in feed volume in the ore bin based on the range of the first bin and the target bin. Determine the sum of the change in material feeding and the first material feeding amount to obtain the second material feeding amount; Adjust the feed rate of the ore bin to the second feed rate.

[0073] In this embodiment, a first feeding amount of the ore bin is obtained, wherein the first feeding amount is the total amount of material fed into the ore bin.

[0074] For example, the sintering system also includes a material mixing tank connected to the ore bin, the material mixing tank being used to mix materials and to convey the sintering mixture to the ore bin.

[0075] If the first slot exceeds the target slot range, it indicates that the feed rate of the ore slot is too high or too low, and the feed rate of the ore slot needs to be adjusted.

[0076] Based on the range of the first and target slots, the change in feed volume in the ore slots is determined, where the change in feed volume is the adjustment amount corresponding to the first feed volume.

[0077] For example, when the first slot is less than the lower limit of the target slot range, the feed amount of the ore slot needs to be increased, and the change in feed amount can be determined as the increase in feed amount.

[0078] For example, when the first slot is greater than the upper limit of the target slot range, it is necessary to reduce the feed rate of the ore slot. The change in feed rate can be determined as the feed rate reduction.

[0079] Determine the sum of the change in material feeding and the first material feeding amount to obtain the second material feeding amount.

[0080] For example, the first feeding amount is updated based on the change in feeding amount to obtain the second feeding amount.

[0081] For example, a fuzzy control algorithm can be used to update the data of the first feeding amount in order to determine the second feeding amount.

[0082] In some embodiments, this application provides a method for controlling the position of the sintering bin in a sintering system. After adjusting the sintering speed of the sintering machine to a second sintering speed, the method further includes: During the operation of the sintering system, the sintering endpoint position and the opening degree of the first air box corresponding to the sintering machine are obtained; The opening degree of the second air box of the sintering machine is determined based on the opening degree of the first air box, the sintering endpoint position, and the preset target endpoint position. Adjust the opening of the sintering machine's bellows to the second bellows opening.

[0083] In this embodiment, the sintering machine includes a bellows. During the operation of the sintering system, the sintering endpoint position and the opening degree of the first bellows corresponding to the sintering machine are obtained. The opening degree of the first bellows is the real-time opening degree of the bellows, and the sintering endpoint position is the real-time sintering endpoint position of the sintering machine.

[0084] For example, the sintering endpoint position and the bellows opening are key operational control parameters in the sintering production process, directly affecting the yield, quality, and energy consumption of sintered ore. Accurately controlling the relationship between these two parameters is an important guarantee for achieving efficient, stable, and energy-saving smelting.

[0085] For example, the sintering endpoint refers to the position of the trolley when the sintering process is completely completed, usually marked by the number of the air box where the exhaust gas temperature is highest.

[0086] For example, the opening degree of the air box refers to the degree of opening of the regulating valve of each air box, which is used to adjust the air volume and negative pressure distribution, thereby affecting the permeability of the material layer, the vertical sintering speed and the endpoint position.

[0087] The opening degree of the second air box of the sintering machine is determined based on the opening degree of the first air box, the sintering endpoint position, and the preset target endpoint position, wherein the opening degree of the second air box is the target opening degree of the air box.

[0088] Adjust the opening of the sintering machine's bellows to the second bellows opening.

[0089] In some embodiments, this application provides a method for controlling the position of the sintering system's ore bin, which determines the opening degree of the second air box of the sintering machine based on the opening degree of the first air box, the sintering endpoint position, and a preset target endpoint position, including: Obtain the endpoint adjustment coefficient corresponding to the sintering endpoint position; Determine the difference between the sintering endpoint position and the target endpoint position to obtain the position difference; The opening degree of the second bellows is determined based on the endpoint adjustment coefficient, the position difference, and the opening degree of the first bellows.

[0090] In this embodiment, the endpoint adjustment coefficient corresponding to the sintering endpoint position is obtained, wherein the endpoint adjustment coefficient is the adjustment coefficient corresponding to the sintering endpoint position.

[0091] The difference between the sintering endpoint position and the target endpoint position is determined to obtain the position difference, where the position difference is the difference between the sintering endpoint position and the target endpoint position.

[0092] The opening degree of the second bellows is determined based on the endpoint adjustment coefficient, the position difference, and the opening degree of the first bellows.

[0093] For example, the formula for calculating the second bellows opening can be: FT 调整后 =FT+Kb×(BTP-BTP 目标）, among which, FT 调整后 FT is the opening of the second bellows, Kb is the end point adjustment coefficient, and BTP is the sintering end point position. 目标 The target endpoint location.

[0094] For example, basic data such as the small ore bin position W1, material layer thickness H, end point position BTP, sintering machine speed V, roller speed S, total feed amount L, and risk opening FT are collected in real time.

[0095] Real-time slot determination: If the slot is within the upper or lower limit range: Parameter settings: Target slot WAIM, slot dead zone W_L, target material thickness HAIM, material thickness dead zone H_L, target endpoint position BTPAIM, endpoint position dead zone BTP_L, deviation ratio coefficient K1, deviation adjustment coefficient K2, machine speed small ratio adjustment coefficient K V1 , Machine speed large-scale adjustment coefficient K V2 Small-proportion adjustment coefficient K for the circular roller S1 , large-proportional adjustment coefficient K of the circular roller S2 1. Endpoint adjustment coefficient Kb. Refer to Table 1 for specific parameter settings.

[0096] For example, the specific values ​​of the above parameters can be set based on historical data of the sintering system.

[0097] For example, a parameter setting model for the sintering system can be established by training the model based on historical data of the sintering system. The parameter setting model is used to determine the specific values ​​of the above parameters.

[0103] If the slot position exceeds the upper or lower limit, and this is the first adjustment cycle, the roller / machine speed adjustment value is first calculated and adjusted based on the condition that it does not exceed the limit, using the same calculation method as described above. Afterwards, a fuzzy control algorithm is used to control the feeding amount.

[0104] Material feeding quantity calculation method: The fuzzy control algorithm is used to control the material feeding quantity. First, the fuzzy control table is formulated, and the universe of discourse of the output error e is set as: E={-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}. Conversion rule: E = P1 × deviation e (round the obtained data); P1 = 6 / emax; Let the universe of discourse for the rate of change of output error ec be: EC = {-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}; EC calculation: EC = P2 × deviation ec (round the obtained data); P2 = 6 / emax; Let the universe of discourse of the control variable u be: U = {-7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}; Feed quantity adjustment value △Y=u; Calculation of u: u = P3 × U; P3 = Umax / 7.

[0105] Fuzzy control lookup table 2 is as follows: Table 2

[0106] The calculated material loading quantity is issued and the adjusted material loading quantity is tracked immediately. The system collects the time of material feed modification and the real-time operating speed of the feeding belt, tracking its movement forward every second as it rotates. When the cumulative operating speed is greater than or equal to the belt length, the system moves to the next belt or the next process for positioning and tracking.

[0107] When the batch of material arrives at the mixing plant, the mixing plant's operating time from inlet to outlet is 'a' minutes. The mixing plant's operating signal is collected once per second and accumulated. When the operating time reaches 'a' minutes, the batch of material arrives at the mixing plant's outlet.

[0108] The tracking calculation method for the second mixture is the same as that for the first mixture.

[0109] Once the new material reaches the small ore bin, monitor the bin position and gradually restore the roller / machine speed to its unadjusted state. Wait for the cycle to proceed with the next assessment.

[0110] If this is not the first adjustment, first determine whether the previous total material quantity adjustment has reached the small ore bins. If the previous adjustment amount has been reached, then calculate E and EC according to the normal procedure, and output the control amount U through the fuzzy control table.

[0111] If the arrival date has not yet been reached, and the direction of this adjustment is the same, no adjustment will be made, and a judgment will be made after the adjusted batch arrives.

[0112] If the adjustment does not reach the target but is in the opposite direction to the current adjustment, the adjustment amount U needs to be increased and the duration is the time from the last adjustment to the current time, after which the normal adjustment amount will be restored. To make it easier to understand, let's take actual production data as an example. Assume that the current tank is 61t, the target tank is 50t, the tank in the previous deviation cycle was 60t, the sintering machine speed is 2m / min, the roller speed is 25Hz, the material thickness is normal, the endpoint position is normal, and the feeding rate is 600t / h. Slot deviation calculation: e=W1-WAIM=61-50=11; Slot trend calculation: ec = W1 - Wold = 61 - 60 = 1; Adjustment value calculation: A = K2(K1×e + (1-K1)×ec) = 0.03×(0.6×11 + (1-0.6)×1) = 0.21; Since the adjustment value exceeds the upper limit, let A = AMAX = 0.2; Increase sintering machine speed: V after adjustment = V + KV2 × A = 2 + 1.2 × 0.2 = 2.24; Roller speed S after adjustment = V after adjustment × S / V = 2.24 × 25 / 2 = 28Hz; The sintering machine speed is set to 2.24 m / min and the roller speed is set to 28 Hz. Continue with the calculation of material feeding adjustment. The calculation method for material feeding control is as follows: First, a fuzzy control table is defined, and the universe of discourse for the output error E is set to {-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}. Let the universe of discourse for the output error e be: E = P1 × deviation e (rounding the obtained data); P1 = 6 / emax = 6 / 30 = 0.2; Then E = P1 × e = 0.2 × 11 = 2; Let the universe of discourse for the rate of change of output error ec be: EC = {-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}; EC is calculated as follows: EC = P1 × deviation ec (round the obtained data). K = 6 / emax = 6 / 8 = 0.75; Then EC = P1 × ec = 0.75 × 1 = 1; Let the universe of discourse of the control variable u be: U={-7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}; by looking up the fuzzy control table, we know that when E=2 and EC=1, U=-4; Calculation of U: u = P3 × U; P3 = Umax / 7 = 42 / 7 = 6; Then u=P3×U=6×-3=-18; Calculation of the feed rate adjustment value (△Y): △Y=u=-24t / h; Feed rate: 600-18=582t / h; The material feeding quantity is issued, and the adjusted material head position is tracked.

[0113] Based on the current feeding quantity, the time is modified, and the real-time operating speed of the feeding belt is 1.6m / s, the belt length is 180m, and the feeding belt start / stop signal S1 is collected. The belt operation signal is 1, and the belt stop signal is 0. The belt moves forward every second, and is tracked in real time. The current adjusted arrival position L1 of the material batch is: L1 = 1.6 × S1 + 1.6 × S1 + ... + 1.6 × S1; When L1≧180, the new batch of material arrives at the mixing belt. Assuming the belt stops for 5 seconds during this process, the batching belt takes 117.5 seconds. The speed of the mixing belt is 1.25 m / s and the belt length is 120 m. The start and stop signal S2 of the mixing belt is collected. The current position L2 of the material batch is: L2 = 1.25 × S2 + 1.25 × S2 + ... + 1.25 × S2; When L2≧120, the new batch of material arrives at the mixing point. Assuming the conveyor belt runs continuously without stopping during this process, the batching conveyor belt takes 96 seconds. The normal time for the batch of material to go from the inlet to the outlet of the primary mixer is 240 seconds. When the batch of material enters the primary mixer, the start / stop signal S3 of the primary mixer is collected in real time. Similarly, the running signal is 1 and the stop signal is 0. The second-level calculation accumulates the operating signal of a mixer into L3, where L3 = S3 + S3 + ... + S3; When L3 ≥ 240, the first batch of material is discharged and enters the conveyor belt before the second batch. Assuming the primary mixer runs continuously without stopping during this process, the first batch takes 240 seconds. The belt speed before the second mixing is 1.25 m / s, the belt length is 100 m, and the start / stop signal S4 of the belt before the second mixing is collected. The current material batch has reached position L4 as: L4 = 1.25 × S4 + 1.25 × S4 + ... + 1.25 × S4; When L4≧100, the new material is batched to the second mixing stage. Assuming the belt runs continuously without stopping during this process, the belt time before the second mixing stage is 80 seconds. The normal time for the batch of material to go from the inlet to the outlet of the secondary mixer is 240 seconds. When the batch of material enters the secondary mixer, the start / stop signal S5 of the primary mixer is collected in real time. Similarly, the running signal is 1 and the stop signal is 0. The second-level calculation accumulates the operating signal of a mixer by L5, where L5 = S5 + S5 + ... + S5; When L5 ≥ 240, the material is discharged from the secondary mixer and enters the conveyor belt after the secondary mixer. Assuming the secondary mixer stops for 10 seconds during this process, the secondary mixing time is 250 seconds. The belt speed after the second mixing is 1.6 m / s, the belt length is 220 m, and the belt start / stop signal S6 before the second mixing is collected. The current material batch has reached position L6 as: L6 = 1.6 × S6 + 1.65 × S6 + ... + 1.6 × S6; When L6≧220, the new material is batched onto the shuttle fabric. Assuming the belt runs continuously without stopping during this process, the belt time after the second mixing is 137.5s. The normal time for the material batch to enter the shuttle fabric is 20 seconds. After the material batch enters the shuttle fabric, the start / stop signal S7 of the shuttle fabricator is collected in real time. Similarly, the running signal is 1 and the stop signal is 0. The second-level calculation accumulates the operating signal of a mixer into L7, where L7 = S7 + S7 + ... + S7; When L7 ≥ 20, the material is fed out of the shuttle cloth and enters the small ore bin. Assuming the shuttle cloth runs continuously without stopping during this process, the shuttle cloth feeding time is 20 seconds. At this point, the new batch of material has entered the small ore bin. Adjust the corresponding machine speed and roller settings back to their original values ​​in two separate adjustments. Monitor the bin position; if the bin position is normal, no further adjustments are needed.

[0114] In some embodiments, such as Figure 2 As shown, an embodiment of this application provides a control device 200 for the position of a sintering system ore bin. The sintering system includes an ore bin, a sintering machine, and a conveying device. The ore bin is used to receive and store the sintering mixture, and the conveying device is used to convey the sintering mixture in the ore bin to the sintering machine. The control device 200 for the position of the sintering system ore bin includes: The acquisition unit 202 is used to acquire the first slot position of the ore bin, the first sintering speed of the sintering machine and the first transmission speed of the transmission equipment during the operation of the sintering system, and to acquire the target slot position range and the second slot position of the ore bin in the previous production cycle. The first processing unit 204 is used to determine the slot deviation between the first slot and the target slot, and to determine the slot change between the first slot and the second slot, provided that the first slot does not exceed the target slot range, and the target slot is the median value of the target slot range.

[0116] Based on the accurate slot deviation and slot change, the first sintering speed is updated to the second sintering speed. Then, based on the first sintering speed and the second sintering speed, the first transmission speed is updated to the second transmission speed, ensuring the accuracy of the data for the second sintering speed and the second transmission speed.

[0117] Adjusting the transmission speed of the transmission equipment to the second transmission speed ensures the stability of the sintering machine's feed, so that the sintering machine is in the most stable feeding state. Adjusting the sintering speed of the sintering machine to the second sintering speed ensures the sintering stability, so that the sintering machine is in the most stable sintering state.

[0118] In summary, by precisely controlling the sintering speed of the sintering machine and the transmission speed of the conveying equipment, the first position of the ore bin is always kept in an optimal state close to the target position. This ensures that the ore bin and the conveying equipment can continuously and stably supply material to the sintering machine, avoid sintering machine shutdown failures, and thus guarantee the overall operational stability of the sintering system.
